coronoidectomy
Pronunciation: kor-oh-noy-DEK-toh-mee
Surgical removal of the coronoid process of the mandible to improve mouth opening.
Full Definition
Coronoidectomy is a surgical procedure involving the removal of the coronoid process of the mandible to increase mouth opening in patients with restricted jaw mobility. The procedure is indicated when the coronoid process interferes with mouth opening due to ankylosis, hyperplasia, or impingement against the zygomatic bone. The surgery can be performed through an intraoral or extraoral approach, with careful attention to preserving the temporalis muscle attachment. Post-operative physiotherapy is essential to maintain the improved range of motion and prevent recurrence of restriction.
Usage
Usage note: Document pre- and post-operative mouth opening measurements for outcome assessment.
